With a starting angular velocity of 140 rad/s (a little bit faster than the example data above), it would spin for 104 seconds. If you want it to spin even longer, then just spin it faster. Doubling the starting angular speed will double the time.With a starting angular velocity of 140 rad/s (a little bit faster than the example data above), it would spin for 104 seconds.

Do fidget spinners spin forever?
Basically, fidget spinners work thanks to nifty low-friction ball bearings that allow the outer mechanism to just spin and spin around its central axis. But even so, eventually the spinner would stop because of friction — or the ball bearing falling apart, whichever comes first.
How do fidget spinners spin for so long?
Fidget spinners are essentially low-friction ball bearings. That’s it. When two objects press against one another, friction prevents them from sliding smoothly. But, thanks to the balls between their surfaces, the races can spin for far longer, subject only to rolling friction.
What fidget spinner spins the longest?
Japanese bearing company NSK has built the longest running fidget spinner at 12 minutes or more. The design uses small, high-precision balls and a weighty brass ring to ensure smooth spinning and maximum centrifugal force.
Can you make a fidget spinner spin forever with magnets?
A magnetic levitation can do the job or so we think. Spinning the top in thin air would, most likely, make it spin for longer, but not forever, because eventually air resistance would make it stop.
Why do fidget spinners have ball bearings?
The ball bearings on the outer parts of the spinner are mainly their for weight. To understand how this works, Doherty offered a simple example. “Think of the ball bearing at one end of a short, thick tongue depressor. Hold the bearing between your thumb and forefinger and let the depressor hang down.
Is friction an advantage or disadvantage of a fidget spinner?
Green 1) Disadvantage because friction would stop the fidget spinner spinning. 2) Advantage because the shoes need to grip the pavement/stop us falling over.
What is the fastest spinning thing?
Scientists at Purdue University have made the fastest spinning object ever, a tiny ball of silicon dioxide that rotates 300 billion times per second. They positioned the microscopic silica balls in a vacuum and blasted them with two different lasers that induce the spin.
What is a female spinner?
Spinner” (Adjective – Slang) Used among some men to describe an extremely petite young woman, usually with a lot of sex appeal – the term is thought to reference the small stature and weight of the woman; (IE she is so petite she could be spun around while riding the man during sex).
Are fidget spinners still popular in 2020?
Fidget Spinner has existed for nearly 25 years now but exploded into world’s attention in 2017. After the initial fascination with Fidget Spinners, most are now passing it out as a fad. Fads, unlike Trends, don’t result in cultural shifts. Trends are usually slow moving shifts in cultural values.
Will something spin forever in space?
A small object like a space ship or an asteroid will just about spin forever, yes. There are a few mechanisms that can reduce rotation of an object in space, for example, tidal forces between the moon and Earth are slowing down Earth’s rotation ever so slightly.
Will a top spin forever in a vacuum?
But, then the vacuum chamber is sealed, and something beautiful happens. In the absence of friction, the top just spins and spins and spins for well over a minute. In theory, if the ground was perfectly level and the vacuum chamber was completely devoid of gases, the top could spin forever. Watch it and get mesmerised.
Is there anything spinning forever?
It’s the perfect gift, designed to last forever. Forever Spin is one of the most recognized spin top company in the world. Look for our authentic holographic serial number and don’t settle for imitations. The titanium top is the most popular top of the ForeverSpin collection.
Has anyone created artificial gravity in space?
However, there are no current practical outer space applications of artificial gravity for humans due to concerns about the size and cost of a spacecraft necessary to produce a useful centripetal force comparable to the gravitational field strength on Earth (g).
Can artificial gravity be created in space by spinning?
Dave: In space, it is possible to create “artificial gravity” by spinning your spacecraft or space station. Technically, rotation produces the same effect as gravity because it produces a force (called the centrifugal force) just like gravity produces a force.
Can a spaceship have gravity?
Yes, there is a gravitational force acting on everything—but there is also that air drag force that will make the spacecraft slow down as it moves down.
Does a fidget spinner have magnets?
First of all, the magnets on the fidget spinner are mounted so that all the magnets have their north pole facing outwards. The electromagnet is wired so that the side that is closest to the spinner will have a north polarity when it is powered.
How fast can ball bearings spin?
Speed Limits Bearing Type Speed Limit Factor Ball, Deep Groove 500,000 400,000 Ball, Angular Contact 450,000 400,000 Cylindrical, 2 Piece Brass Cage 550,000 475,000 2 Piece Steel Cage 450,000 380,000.
Does fidget spinner increase concentration?
For children with ADD or ADHD, certain repetitive movements may allow for better concentration. Objects such as squeeze balls or stress balls require that the individual do the movement. By physically engaging in movement, focus on other tasks may improve. So, no, fidget spinners don’t boost kids’ concentration.
How many bearings does a fidget spinner have?
So we’ve established that the vast majority of fidget spinners out there use 608 bearings.
Why do fidget spinners work?
The mechanism behind the spinners is relatively simple. As any spinning apparatus, fidget spinners rotate around a central axis, formed by two rings. By using a ball bearing mechanism instead of simple sliding between the rings, friction may be reduced significantly during rotation.
Is friction advantage in running shoes?
Running shoes: Friction would be an advantage because the shoes need to grip the pavement. Bicycle brakes: Friction would be an advantage because it would allow the bicycle to stop. Slippery slide: Friction would be a disadvantage because it would make it difficult to slide.
What can I do with old fidget spinners?

Who created fidget spinners?
Who Invented the Fidget Spinner? Catherine Hettinger is often credited as the inventor of fidget spinners. She came out with the idea for the spinning toy back in 1993, but her original prototype was rejected by Hasbro.
Does RPM mean revolutions per minute?
Revolutions per minute.
